My kids have University Loft Furniture. We got it at Art Van and we LOVE it! It is "modular" and so versatile...we switch it around all the time (just did so again yesterday!) Here is a link to their website...I hope it works. http://www.universityloft.com/category-view.aspx?category...
There are several different collections in different color finishes. Beds can be regular height beds, loft height, or bunkbed height. Desks, dressers, shelves, chairs, can fit under depending on which height you have the furniture set up at. My kids also like to have nothing under the loft height bed and use it like a fort or Lego play area. It is not cheap, but since it is built for college dorm rooms (those can get a bit rowdy!) it is very durable and super easy to take apart and put back together. You don't even need a screwdriver to take them apart and move them around. I figured these would be the only beds I would ever buy my kids...and hopefully they can take them with them when they move out!
Good luck!
